• ffmpeg with a python wrapper— need help avoiding multiple passes on a file

  19 octobre 2018, par Dean D D

  I would like some help refactoring this code to reduce the amount of passes ffmpeg must make on the file. I figure creating a single compounded ffmpeg command would do the trick, but I am kind of lost.

  def processVideo(videoFile, venueWatermarkFile, companyWatermarkFile, mp3File=None, m4vFile=None, cropH, cropW, resizeH, resizeW):
  
      if mp3File != "" :
  
          subprocess.call('ffmpeg -y -i ' + videoFile + ' -i ' + audio + ' -filter_complex "[0:v]scale=480:ih*480/iw, crop=480:480, loop=loop=3:size=210, trim=duration=15[video]" -shortest -map "[video]" -map "1:a?" -c:a aac new1.mp4', shell=True)
  
      else :
  
          subprocess.call('ffmpeg -y -i ' + videoFile + ' -i ' + audio + ' -vf "scale=480:ih*480/iw, crop=480:480" new1.mp4', shell=True)
  
  
  
      if m4vFile != "":   
  
          subprocess.call('ffmpeg -i ' + videoFile + ' -i ' + m4v + ' -filter_complex " [0:v] scale=480:ih*480/iw, crop=480:480 [bg]; [1:v] chromakey=00FF00:similarity=0.2:blend=0.3 [fg]; [bg][fg] overlay=shortest=1 [v] " -map "[v]" -map "0:a?" -f mp4 new1.mp4', shell=True)
  
  
  
      subprocess.call('ffmpeg -y -i new1.mp4 -i ' + venueWatermarkFile + ' -filter_complex "overlay=0:0" -codec:a copy new2.mp4', shell=True)
  
      subprocess.call('ffmpeg -y -i new2.mp4 -i ' + companyWatermarkFile + ' -filter_complex "overlay=0:0" -codec:a copy new.mp4', shell=True)
  
  
  
      subprocess.call('ffmpeg -y -i new.mp4 new.gif -hide_banner', shell=True)
  
      subprocess.call('ffmpeg -y -i new.mp4 -ss 00:00:00.000 -vframes 1 new.jpg', shell=True)
  
  
  
      os.remove("new1.mp4")
  
      os.remove("new2.mp4")
  
  
  
  
  
  processVideo("video-standard.mp4", "venue-standard.png", "company-standard.png", "clip.mp3", "animation.m4v")

• How to send traffic to all pods of service instead of round robin method in kubernetes

  10 janvier 2018, par MDK

  I want to build a cluster that contains a single pod that running ffmpeg to convert input video to different qualities and send the result to a nginx cluster to serve it.
  for nginx cluster I have a kubernetes service.
  if ffmpeg pod wants to push video (which is in rtmp format) to nginx cluster each nginx pod receive some part of video and when a user connects to nginx from outside just get some packets.
  because when ffmpeg pod send video to nginx service kubernetes send packet to nginx pods in round-robin all nginx pods can not get full live video traffic.
  so I need to send traffic from ffmpeg to all pods of nginx services.
  but I don’t know how should I change routing methods to achieve this.
